What are some use cases for the publish-subscribe pattern?
The publish-subscribe pattern is widely used in messaging systems. Common use cases include event notification, real-time data feeds, and decoupling microservices.
Can you give me an example of event notification?
Sure! A classic example is a stock market application where users subscribe to updates for specific stocks. When there's a price change, the system publishes a notification to all subscribers.
How does it help in decoupling microservices?
By using the publish-subscribe pattern, microservices can communicate without knowing about each other. This allows for easier scaling and maintenance.
What technologies commonly implement this pattern?
Technologies like Apache Kafka, RabbitMQ, and Google Cloud Pub/Sub are popular for implementing the publish-subscribe pattern.
